Nature of small-scale Ca II H brightenings associated with weak fields in a quiet Sun region
Xiang Li, H. N. Smitha, S. K. Solanki +3
Context. Chromospheric emission observed in the Ca II H and K resonance lines is generally positively correlated with photospheric magnetic fields. However, a fraction of strong Ca…
Origin of small-scale evaporation flows deep in the chromosphere during a solar flare
L. P. Chitta, H. N. Smitha, F. A. Iglesias +29
Flares are caused by an abrupt release of magnetic energy in the solar atmosphere. Plasma heated to well over 10 MK filling the post-flare corona originates from a rapid heating an…
Elemental Composition Evolution during the 2024 September 30 Solar Eruption: A Comparison of Hot and Cool Plasma Components with Solar Orbiter/SPICE, Hinode/EIS, and Chandrayaan-2/XSM
Momchil Molnar, Joseph Plowman, Amir Caspi +7
Solar plasma composition differs between the photosphere and corona over a range of timescales, with preferential enhancement of elements with low first ionization potential (FIP).…
Exploring if a coronal dimming event can produce coronal hole-like properties
Adriana De-Sassi, Louise Harra, Krzysztof Barczynski +8
Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. We investigate…
Height Dependent Phase Shifts of Wave Pulses in the Lower Solar Atmosphere Measured with SUNRISE III
Andreas Lagg, H. N. Smitha, Sami K. Solanki +32
We report on the measurement of the height-dependent time shifts of wave pulses in the lower solar atmosphere from high-resolution spectro-polarimetric observations obtained with t…
Solar flare ribbons structured by uncombed chromospheric loops
L. P. Chitta, E. R. Priest, David Orozco Suárez +33
A part of the magnetic energy released during a flare is transported to the lower atmosphere. High-resolution observations show that flare ribbons, sites of energy deposition at th…
